NEUTRON BEAM DETECTION DEVICE, AND NEUTRON CAPTURE THERAPY DEVICE

摘要

PROBLEM TO BE SOLVED: To inhibit decrease in the accuracy of calculation of a neutron beam dose.;SOLUTION: A neutron beam detection device that detects a neutron beam comprises a scintillator 13 that generates light when radiation enters it, an optical fiber 14 that transmits the light generated by the scintillator 13, and a dose calculation unit 21 that calculates a dose of the neutron beam on the basis of the light transmitted by the optical fiber 14. The optical fiber 14 comprises a reflection part 14d that causes the light to be reflected diffusely at a wall of the scintillator 13 side end.;COPYRIGHT: (C)2015,JPO&INPIT
